Instead of stiff legged deads, do romanian deads. They look the same, but in romanian deads there is a little more of a slight bend in your knees, which makes a huge difference in your hamstring, and it still hits your lower back. With stiff legged deads, its not good to lock out your legs putting so much pressure on your back. You can get away with it.....until it bites you in the ass. Just a suggestion.

But as far as your routine, i dont want to comment too much before i you are trying to accomplish. With that said, you should be including dips and pullups in your routine
